RN-Severnaya Neft

RN-Severnaya Neft, Rosneft’s key producing asset in the Timan-Pechora Province, operates 20 licence areas (with Rosneft and RN-Nyaganneftegaz as the subsoil users) in the Republic of Komi and the Nenets Autonomous Area. The bulk of proved reserves (70%) are concentrated in five fields, including the Labaganskoye, Naulskoye, Khasyreyskoye, Srednemakarikhinskoye and Cherpayuskoye fields.

In 2019, RN-Severnaya Neft produced 2.8 mmtoe of hydrocarbons, including 2.7 mmt of liquid hydrocarbons.

In 2019, RN-Severnaya Neft drilled and commissioned 10 multilateral wells with an average initial flow rate of 55 t per day, which is two times higher than that of similar horizontal wells. The share of multilateral wells amounted to 20% of all new wells in 2019 (vs 8% in 2018).

RN-Severnaya Neft continues hydraulic fracturing operations on previously drilled wells (12 operations in 2019 vs 2 in 2018). The average initial flow rate amounted to 18.3 t per day, which resulted in 29.8 kt of incremental production.

RN-Severnaya Neft was ramping up its squeeze cementing efforts with 17 operations to inject visco-elastic mud into production wells (vs 2 in 2018), which translated into 20 kt of recovered production.

In March 2019, the Labaganskoye field commissioned a modular cluster pumping station as the final step towards completion of the reservoir pressure maintenance system. In 2019, voidage replacement amounted to 115%.

Bashneft-Polyus

Bashneft-Polyus operates a development project covering the Trebs and Titov fields located in the Nenets Autonomous Area.

In 2019, it produced 1.2 mmtoe of hydrocarbons (up 2.2% year-on-year). Bashneft-Polyus commissioned 23 new wells (2.3x increase year-on-year) with the average initial flow rate rising by 27% to 195 t per day. In 2019, it also started production drilling at the Obsedinskaya area of the Trebs field.

Bashneft-Polyus successfully ran pilot tests, including three drilling operations using a 323.9 mm wide casing string in the 45–512 m interval and two controlled pressure drilling operations.
